PROBLEM TO BE SOLVED: To provide electrolyte for an electrolytic capacitor having low impedance characteristics, high breakdown voltage characteristics of 100V class and good high temperature lifetime characteristics, and to provide an electrolytic capacitor using it. SOLUTION: The electrolyte for an electrolytic capacitor contains aluminium salt tetrafluoride and a high melting point solvent, e.g. sulfolane, 3-methylsulfolane, or 2, 4-dimethylsulfolane. An electrolytic capacitor having low impedance characteristics, high breakdown voltage characteristics and good high temperature lifetime characteristics is thereby obtained. COPYRIGHT: (C)2004,JPO
